Spined Micrathena

Micrathena? Greetings, Whats That Bug?!, This curious-looking spider has taken up residence on our front porch. It is only about 1 cm long, and violently shakes its web when disturbed. After looking at Bugguide, I believe it is a Spined Micrathena http://bugguide.net/node/view/1996 . Nonetheless, I thought the close-ups might be good enough to help some WTB? viewers to ID this neat little critter. Regards, Emily
